NINGBO INNO PHARMCHEM CO.,LTD. is pleased to introduce its premium product, WS Curing Resin, a highly effective thermoplastic p-t-octyl phenol-formaldehyde reactive resin. This versatile material is presented in a solid form, typically available as a powder or transparent flaky solid, making it convenient for various industrial applications.

Our WS Curing Resin is characterized by its precise chemical composition and consistent quality, ensuring reliable performance in diverse rubber formulations. Typical properties that define its efficacy include a softening point ranging from 85-95ºC (Ring&Ball method), a low water content of ≤1.0%, and a critical methylol content of 8-12%. These parameters are carefully controlled during manufacturing to guarantee batch-to-batch consistency and optimal reactivity.

The primary application of WS Curing Resin is its role as a potent curing agent in the rubber industry. It is particularly effective with Natural Rubber (NR) and various Synthetic Rubbers (SR), including Isobutylene Isoprene Rubber (IIR), Ethylene Propylene Diene Monomer (EPDM), Nitrile Butadiene Rubber (NBR), and Chloroprene Rubber (CR). Its reactive nature facilitates the cross-linking process within the rubber matrix, leading to enhanced physical and chemical properties in the final vulcanized product.

When using WS Curing Resin as the sole curing agent, the inclusion of appropriate catalysts is necessary to activate the curing reaction. Recommended catalysts include CR (used at 5-8% of rubber weight) or SnCl2 (used at 2-5% of rubber weight). Reference usage levels for specific rubber types further illustrate its versatility: approximately 7-12% of IIR weight and 1.5-2% of EPDM weight are commonly recommended to achieve desired curing characteristics.

The benefits of incorporating WS Curing Resin into rubber formulations are significant. It contributes to improved heat resistance, increased hardness, enhanced tensile strength, and better compression set properties. These improvements are crucial for extending the lifespan and performance of rubber components in demanding environments across automotive, construction, and other industrial sectors. Its consistent performance ensures predictable curing cycles and reliable end-product quality.

At NINGBO INNO PHARMCHEM CO.,LTD., quality control is paramount. We utilize high-grade raw materials and maintain stringent quality checks throughout our manufacturing process. Our commitment ensures that every batch of WS Curing Resin meets the required specifications and delivers the high performance our customers expect. We understand the critical nature of raw materials in production processes and strive to be a trusted partner.

Packaging for WS Curing Resin is designed for safe handling and storage, typically supplied in 25kg (net weight) kraft bags with an inner PE coating. Proper storage is essential to maintain product integrity; it should be kept indoors in a dry and well-ventilating area, protected from excessive heat and potential fire sources. Under these conditions, the storage life is typically one year from the date of manufacturing.
